The allowable load curve defines the limits at which the lug is expected to fail -- it defines the ultimate load for a given combination of applied axial and transverse load.

A lug can be described as a ‘single bolt fitting’ – typically used to transmit large loads and provide a joint that can quickly be disconnected.

Lugs are connector-type elements widely used as structural supports for pin connections. In the past, the lug strength was overdesigned since weight and size requirements were for the most part unrestricted. However, the refinement of these requirements have necessitated conservative methods of design.

Define the geometry of the lug, including dimensions such as diameter, thickness, and fillet radii. Identify the applied loads, including axial forces, shear forces, and moments.

Figures 9-21 and 9-22 show the lug and the range of lug geometries covered by the fatigue strength prediction method. Fatigue lives for lugs having dimensional ratios falling outside the region shown should be corroborated by tests. In this method the important fatigue parameters are k 1, k 2, and k 3 (see Figure 9-23).

The Lug Analysis calculator allows for analysis of lifting lugs under axial, transverse, or oblique loading. This calculator follows the Air Force Method as documented in the Stress Analysis Manual of the Air Force Flight Dynamics Laboratory (FDL).

We have used this as the basis for our lug analysis spreadsheets. All of the curves are fully digitized. There is a spreadsheet for each of the individual failure modes : AA-SM-009-001 Lug …

2022年3月21日 · “TEL” is defined along the engine’s lug curve. “Engine Accel. Rate” “Engine Accel. Rate” determines the rate of change of the engine speed (acceleration or deceleration) during PTO operation. This rate of change is also used to achieve intermediate engine speed. “Low Idle Speed” is the minimum allowable operating speed for the engine.

2006年6月6日 · Most lug curves, universally, are cut off at Aav/Abr = 1.4, so I extrapolated the curves to align with your given lug configuration. The data I have for 6061-T6 is based on aerospace practice and in-house testing.
